I used tools like Photoshop and Illustrator to design each piece. My focus was on making sure the typography was bold and readable, and the visuals highlighted the main subject clearly. In categories like gaming or boxing, I leaned into energetic visuals and high contrast. For podcasts and electronics, I kept it more structured and minimal. Despite the variety, I maintained consistency in quality and design logic. The final results showed a clear difference. Thumbnails looked more polished, engaging, and aligned with the target audience. Compared to earlier versions, the new designs were more attention-grabbing and likely to drive better engagement.
